Abstract Hormonal changes and metabolic needs during pregnancy result in profound changes in biochemical parameters of thyroid function, especially if there is preexsisting autoimmune thyroid disease (AITD). Normal thyroid function is important in order to ensure the best outcome. Many changes in the functioning of the thyroid gland occur during pregnancy, and some diseases of thyroid gland can affect both mother and fetus. Hypothyroidism is the most serious disorder that occurs during pregnancy and can go unnoticed as a „non-specifi c” problem. Hypothyroidism arises from the reduced ability of the gland to adapt to the increased needs during pregnancy. Mild thyroid dysfunction of mothers in the fi rst trimester, which does not threaten during the pregnancy, can damage the psychomotor development of the child. Measurement of TSH is the most practical, simple and cost- eff ective screening test for thyroid dysfunction. It is necessary to apply the trimester-specifi c TSH reference values to correctly interpreted thyroid function during pregnancy. Th e presence of TPOAb is confi rmation of existence of AITD, and predicts increased risk of developing subclinical hypothyroidism (SH). Preconceptional education and adequate diagnosis and treatment of thyroid dysfunction in early pregnancy are of great importance, in order to prevent complications during pregnancy and off spring. Current data indicate an increase in pregnancy loss, gestational diabetes, gestational hypertension, pre-eclampsia and preterm delivery in women with SH in pregnancy. Th e control of thyroid disease reduce complications of pregnancy.

Background First-trimester care of maternal thyroid dysfunction has previously been shown to be poor. This study evaluates early management of thyroid dysfunction in pregnancy in Australia. Methods Patients reviewed by the Obstetric Medicine team for thyroid dysfunction from 1 January 2012 to 30 June 2013 were included. Data were collected on gestation at referral from the patient’s general practitioner to the antenatal clinic, information provided in the referral letter, thyroid function tests and thyroid medications. Results Eighty-five women were included in the study. At the time of general practitioner referral to antenatal services, 19% of women with preexisting thyroid disease had no thyroid function tested. Forty-three percent had an abnormal thyroid-stimulating hormone defined as being outside the laboratory-specific pregnancy reference range if available, or outside the level of 0.1–2.5 mIu/L in the first trimester, 0.2–3.0 mIu/L in the second trimester and 0.3–3.0 mIu/L in the third trimester. Only 21% of women increased their thyroxine dose prior to their first antenatal clinic review. Conclusion This study highlights that a significant proportion of women with known thyroid disease either have untested thyroid function in the first trimester or a thyroid-stimulating hormone outside of levels recommended by guidelines.

The spectrum of thyroid disease in pregnancy has implications for both the mother and the developing fetus. Here we review the interpretation of thyroid function test values, thyrotoxicosis, hypothyroidism, iodine requirements, autoimmune thyroid disease, and thyroid screening recommendations as they pertain to pregnant women. It should be noted that the management of thyroid dysfunction in pregnancy should be closely co-ordinated with obstetricians and other providers.

Abstract On the basis of low specificity, poor positive predictive value, and cost, there is at present no basis for routine assessment of thyroid function in acutely hospitalized patients, unless clinical features suggest the possibility of thyroid dysfunction, or a patient's background increases the likelihood of thyroid dysfunction. When used in severely ill patients, estimates of both thyroxine (T4) and thyrotropin (TSH) show a high prevalence of abnormal results, but lack specificity and have poor positive predictive value for true thyroid disease. When thyroid function is tested in the critically ill, the positive predictive value for true thyroid disease of both free T4 and TSH measurements could be improved by using wider reference intervals than for unselected populations. The knowledge of nonspecific disease-related abnormalities of triiodothyronine, T4, and TSH is not currently likely to yield useful prognostic information or to alter management for individual patients. Thyroid testing should be readily available for any acutely ill patient with any clinical features that suggest thyroid dysfunction, and for groups at increased risk of thyroid dysfunction. An initial abnormal result for either TSH or free T4 estimate should be followed by combined analysis of free T4 and TSH with the best available methodology. Diagnosis of thyroid dysfunction should be based on the T4-TSH relation rather than either value alone. Persistence of an apparent diagnostic abnormality should be confirmed before therapy is commenced.

There is a high incidence of thyroid dysfunction during pregnancy resulting in adverse maternal (miscarriages, anaemia in pregnancy, preeclampsia, abruptio placenta and post-partum haemorrhage) and fetal effects (premature birth, low birth weight, increased neonatal respiratory distress) which may justify screening for thyroid function during early pregnancy with interventional levothyroxine therapy for thyroid hypofunction. There is a greater prevalence of subclinical hypothyroidism in women with delivery before 32 weeks and there is even an association between thyroid autoimmunity and adverse obstetric outcome, which is independent of thyroid function. Higher maternal TSH levels even within the normal reference range are associated with an increased risk of miscarriages, fetal and neonatal distress and preterm delivery. There are few prospective randomised trials to substantiate the benefit of screening and the recently reported CATS study did not show a benefit in child IQ at age 3 years. Nevertheless there seems to be a case for screening to prevent adverse obstetric outcomes. The clinical epidemiological evidence base does not justify universal screening at the present time. However, it is probable that more evidence will be produced which may alter this view in the future.

Disturbance of the thyroid function is often detected in patients with different profiles. A special feature of patients with chronic kidney  disease is the higher incidence of various thyroid function  disturbances, especially hypothyroidism. It is known that in patients  with chronic kidney disease (CKD) iodine excretion from the body is  violated, since normally 90% of iodine is excreted in urine.  Accumulation of high concentrations of inorganic iodine leads to the  formation of the Wolf-Chaikoff effect: suppression of iodine  organization in the thyroid gland and disruption of the thyroid  hormones synthesis. Peripheral metabolism of thyroid hormones is  also disturbed, namely, deiodinase type I activity is suppressed and  peripheral conversion of T4 into T3 is inhibited (so-called low T3  syndrome). Therefore, patients with CKD are often diagnosed with  hypothyroidism, and the origin of hypothyroidism is not always  associated with the outcome of autoimmune thyroiditis. The article  presents an overview of a large number of population studies of  thyroid gland dysfunction in patients with CKD, as well as  experimental data specifying the pathogenetic mechanisms of  thyroid dysfunction in patients with CKD. Therapeutic tactics are still  not regulated. However, in a number of studies, replacement therapy with thyroid hormones in patients with CKD had some advantages.

Background: This systematic review and meta-analysis summarizes the evidence for the association between endometriosis and adverse pregnancy outcome, including gestational hypertension, pre-eclampsia, low birth weight, and small for gestational age, preterm birth, placenta previa, placental abruption, cesarean section, stillbirth, postpartum hemorrhage, spontaneous hemoperitoneum in pregnancy, and spontaneous bowel perforation in pregnancy. Methods: We performed the literature review in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA), by searches in PubMed and EMBASE, until 1 November 2020 (PROSPERO ID CRD42020213999). We included peer-reviewed observational cohort studies and case-control studies and scored them according to the Newcastle–Ottawa Scale, to assess the risk of bias and confounding. Results: 39 studies were included. Women with endometriosis had an increased risk of gestational hypertension, pre-eclampsia, preterm birth, placenta previa, placental abruption, cesarean section, and stillbirth, compared to women without endometriosis. These results remained unchanged in sub-analyses, including studies on spontaneous pregnancies only. Spontaneous hemoperitoneum in pregnancy and bowel perforation seemed to be associated with endometriosis; however, the studies were few and did not meet the inclusion criteria. Conclusions: The literature shows that endometriosis is associated with an increased risk of gestational hypertension, pre-eclampsia, preterm birth, placenta previa, placental abruption, cesarean section, and stillbirth.

Целью научной работы является изучение структуры заболеваний щитовидной железы у больных сахарным диабетом 1 типа. В данной статье мы ретроспективно проанализировали 972 историй болезни больных детей с СД 1 типа, находившихся на стационарном лечении в ДГКБ №2 г. Алматы (Казахстан) в период с 2014 по 2019 гг. Были изучены и оценены показатели физического развития, объективные данные (кожные покровы, ЧСС, АД, пальпация ЩЖ), лабораторно - уровней гормонов ТТГ, свТ4, свТ3, а/т к ТПО, а/т к ТГ в сыворотки крови, инструментально - УЗИ ЩЖ. Всего за 2014-2019 гг. через отделение эндокринологии ДГКБ №2 прошли 972 детей с диагнозом СД 1 типа. Большинство детей (382 человек, 79,9%) имели стаж болезни СД до 5 лет. 88 детей (18,5%) со стажем от 5 до 10 лет, 8 человек (1,7%) страдали СД более 10 лет. СД1 в основном был диагностирован в возрасте 7-12 лет (245-51,3%), меньше всего выявили СД 1 типа у детей до 3 лет (21 - 4,4%). Из общего количества пациентов с СД1 (972) было обследовано на функцию ЩЖ 478 детей (49,2%). Среди них было выявлено 319 детей с дисфункцией ЩЖ, что составляет 66,7%. Так, за 2014 год из 92 детей - 7 (7,6%), обследованных на функцию щитовидной железы, в результате чего было выявлено 6 (85,7%) детей с дисфункцией щитовидной железы. С каждым годом росло количество детей, которых направляли на обследование ЩЖ, так в сравнении с 2014 годом, когда из 92 детей - 7 (7,6%) были обследованы на функцию щитовидной железы, в 2019 году были обследованы уже 222 (92,1%) детей из 241. Симптомы как гиперфункции, так и гипофункции ЩЖ, особенно их субклинические варианты протекают под маской других заболевании и не сразу обнаруживаются, исходя из этого следует сразу обследовать на функцию ЩЖ при поступлении и в дальнейшим их наблюдать в динамике. В ходе исследования дисфункция щитовидной железы диагностирована у 319 (67,7%) пациентов, что должно привлечь внимание не только эндокринологов, но и врачей общей практики, педиатров и настроить их на прицельный поиск этой патологии и своевременную коррекцию гипотиреоза или другой патологии ЩЖ при его наличии The purpose of this research is to study the structure of thyroid diseases in patients with type 1 diabetes. In this article, we retrospectively analyzed 972 case histories of sick children with type 1 diabetes who were treated in the children's city clinical hospital No. 2 in Almaty (Kazakhstan) in the period from 2014 to 2019. Physical development indicators, objective data (skin, heart rate, blood pressure, thyroid palpation), laboratory levels of TSH, thyroxine, triiodothyronine, antibodies to thyroperoxidase, antibodies to thyroglobulin in blood serum, instrumental ultrasound examination of the thyroid gland were studied and evaluated. In total, in 2014-2019, 972 children with a diagnosis of type 1 diabetes mellitus passed through the endocrinology Department of the children's city clinical hospital No. 2.The majority of children (382 people, 79.9%) had a history of diabetes up to 5 years. 88 children (18.5%) with experience from 5 to 10 years, 8 people (1.7%) had diabetes for more than 10 years. Type 1 diabetes was mainly diagnosed at the age of 7-12 years (245-51. 3%), the least detected type 1 diabetes in children under 3 years (21 - 4.4%). Out of the total number of patients with type 1 diabetes (972), 478 children (49.2%) were examined for thyroid function. Among them, 319 children with thyroid dysfunction were identified, which is 66.7%. So, in 2014, out of 92 children, 7 (7.6%) were examined for thyroid function, as a result of which 6 (85.7%) children had thyroid dysfunction. Every year, the number of children referred for thyroid examination increased, so compared to 2014, when out of 92 children - 7 (7.6%) were examined for thyroid function, in 2019, 222 (92.1%) children out of 241 were examined. Symptoms of both hyperfunction and hypofunction of the thyroid gland, especially their subclinical variants, occur under the guise of other diseases and are not immediately detected, so you should immediately investigate the function of the thyroid gland at admission and further observe them in dynamics. During the study, thyroid dysfunction was diagnosed in 319 (67.7%) patients, which should attract the attention of not only endocrinologists, but also General practitioners, pediatricians and set them up for a targeted search for this pathology and timely correction of hypothyroidism or other thyroid pathology if it is present.

Abstract BACKGROUND: Pregnant women with obesity are at increased risk for peripartum depression. Maternal obesity is also associated with reduced human placental lactogen (hPL) levels, and decreased hPL transcripts were reported in women with clinical depression. In addition, hPL production may be rescued in women with obesity that were subsequently diagnosed with gestational diabetes and treated with insulin (INS). Objective: Study the effect of INS treatment in pregnancy on the risk for postpartum psychological distress (PPD) in women with and without obesity. Study Design: Using data housed at the Manitoba Centre for Health Policy (2002–2017), cohorts of women (ages 15+) with a single live birth with and without obesity were developed using weight (≥85 and <65.6 kg, respectively) and an average (1.63 m) height. Pre-existing mood and anxiety disorders within 5 years preceding delivery as well as gestational hypertension were excluded. After randomly selecting 1 birth per mother, cohorts were stratified by INS treatment during the gestational period. The risk of PPD within 1 year of delivery was assessed by Poisson regression analysis. Models were adjusted for maternal age and area-level income at delivery. Results: The risk of PPD was 27% greater among women with obesity versus without (adjusted rate ratio (aRR)=1.27, 95% CI 1.16–1.4, p<0.0001). However, women with obesity treated with INS did not have a significantly different risk of PPD compared to women without obesity whether treated with INS (aRR=0.99, 95%CI 0.48–2.02, p=0.974) or not (aRR=1.16, 95%CI 0.86–1.56, p=0.328). This suggests that the risk of PPD among women with obesity may be reduced by INS treatment; however, our ability to detect a significant difference may be limited by small cohort numbers (46 women with obesity received INS in pregnancy) or confounders for receiving INS in pregnancy. Direct comparison of INS treatment within weight groups faced the same limitations but trended toward a reduction in women with obesity who received INS (aRR=0.91, 95%CI 0.68–1.22, p=0.531). The positive association between INS treatment in pregnancy and decreased risk of PPD in women with obesity was lost when pre-existing mood and anxiety disorder was not excluded. Inclusion of pre-existing diabetes in the adjusted models did not improve model fit or contribute significantly to the differences in PPD rates. Conclusions: Maternal obesity increases the risk for PPD but this risk may be reduced by gestational INS treatment in the absence of a pre-existing mood and anxiety disorders. This correlates with the decrease and increase in hPL levels reported previously with maternal obesity without and with INS treatment (for diabetes) in pregnancy, respectively. Thus, hPL levels may serve as a possible indicator of PPD risk and a potential target for gestational INS treatment.

Disorders of thyroid function are common in pregnancy and have implications for foetal and maternal health. Thyroid autoimmunity, as evidenced by the presence of elevated levels of anti-thyroid antibodies (anti-TPO and anti-Tg antibodies) is associated with an increased risk of miscarriage, though the mechanism remains poorly understood. There has been considerable focus on the implications and optimal management of pregnant women with thyroid disease, especially those undergoing assisted reproduction. Pregnancy results in significant changes in thyroid physiology and these need to be understood by clinicians involved in the care of pregnant women. Guidelines for the use of thyroxine and target thyroid function tests have been produced by international bodies but it is recognised that these predominantly reflect expert opinion rather than established evidence-based practice. Importantly a number of key clinical trials have been performed to aid understanding, particularly of the consequences of hypothyroidism for mother and baby, and the effectiveness of thyroid hormone use in autoimmune and subclinical hypothyroidism. This review summarises the current knowledge base and guidance for practice relating to thyroid disorders in pregnancy and subfertility.

Abnormal function of thyroid gland is associated with a disturbance in the menstrual cycle. However, in clinical practice, thyroid dysfunction is frequently overlooked as a possible etiology and therefore, the importance to investigate thyroid function in asymptomatic cases is under- recognized in India. Treating thyroid dysfunction in such cases can reverse the menstrual abnormality, thus avoiding unnecessary hormonal therapy or in long term, hysterectomy. This article is intended to determine the prevalence of overt and subclinical forms of hypothyroidism/hyperthyroidism among women with abnormal uterine bleeding (AUB) in a known iodine-deficient state of India, Chhattisgarh. Moreover, the aims included to characterize the types of menstrual abnormality with thyroid dysfunction in study participants. The present study found a prevalence of thyroid dysfunction in one out of five cases of menstrual abnormality, most common dysfunction being hypothyroidism. An appreciable proportion of thyroid disorder was found in patients with menorrhagia, oligomenorrhea, polymenorrhea and amenorrhea.
